After you’ve set up and enabled Guest mode, lock the screen, then
press the Power/Lock Key to re-display the Lock
screen. Enter your Guest mode pattern. The Guest mode Home screen
is displayed with only the apps you’ve selected for guest access.
To exit Guest mode, simply access the Lock screen again and enter
your normal unlock pattern.
The Guest mode feature is automatically turned off if your lock sequence is changed from Pattern. Otherwise, manually disable it if you no longer want to allow guest access.
